A veteran Bronx assemblywoman has been removed from the New York primary ballot due to petition fraud allegations.

Amanda Septimo accused Carmen Arroyo's campaign of collecting illegally backdated petition signatures so she could get on the ballot for the upcoming Democratic primary.

Septimo, 29, alleges Arroyo's campaign picked up petition sheets on Feb. 27. Septimo says she discovered 41 pages of signatures that the incumbent submitted to the Board of Elections that were dated Feb. 25 and 26.

Arroyo and Septimo were both competing to be the Democrat on the ballot for the 84th Assembly District in the general election in November.

Septimo says when she suspected fraud, she filed a case against her opponent in Bronx Supreme Court, losing at that level and the appellate division.

The challenger took her case to the Court of Appeals, which decided Thursday to overturn the ruling, stating in a decision document that "the lower courts should have concluded that this is one of those rare instances in which the designated petition is so permeated by fraud as a whole as to call for its invalidation."

The 29-year-old is now celebrating her victory.

"So many people lose faith in politics and you feel sometimes like these systems are flawed," Septimo says. "It was kind of validating to know that sometimes things are a little rigged against you."

Septimo is now preparing for the general election in November.

News 12 reached out to Arroyo but has yet to get a response.
